lTo all whom t may-concern: l

'Be it known that we, BENJAMIN ADRiANcn 'and'AMoS OA-LLESON, citizens ofthe United States, residing in Brooklyn, in the county of 5 Kings andStateof New York, have invented certain new yand useful Improvements inl Sheet-Metal Boxes'or Cans; and we do hereby declare the following tobe afull, clear, and exact description of t-he invention, such io' aswill enable'others skilled in the art to which it appertains-tomake anduse the same, referencebeinghad to the accompanying drawings,

and to characters of referencev marked thereon, which .form a part ofthis specification. i 5I' This invention relatesto improvements in orother vessels, and it has reference particular'ly to theformation of thejoint or seambetween the body and head of such vessels.

' and 700,57 8.; but in practical operation such methods are-slow andexpensive, require spe- 45., cial tools and machines, and are or may beattended with danger of breaking or cracking thestock andotherdiffunilties.v

I' sists, that such seams may be made hermetically tight l.bylongitudinally grooving one .side ol the seam, while its opposite side.is

Surfaces of the sever-a1 folds of he Seam are I brought into close andperfect contact and compacted together along the line of thelonvgitudinal groove extendingl the? length of the seam or around thecan, thus producingan hermetically-tight seam or closure. A The seamthereby produced and embodying our invention, it'will thus beunderstood, consists of one or more plain smooth vfoldsat one .side

'and ,pf one or more 'longitudinally-grooved folds atthe opposite sideofv the seam or for theiremai'nderof its thickness and that the;

7'5 nessalong the line of its longitudinal groove;- y than it is atother parts or adjacent to ,suche` seam as a-whole is of -materiallyless thickgroove, In practicing our invention one side ofthe-seam,preferably'theinside-thereof,isv y' part ol"l thisspecification, we have for con-.I

venience, illustrated our invention as practiced with and applied .towhat is commonly known to those skilled in the art as a double 7 O-v 1of theseam orpart-way through its thioknss a sea1n-a seam composed offive foldsor thick- It will be understood, however, that' Inv thedrawings, Figure l is a side eleva- I tion of a canor vessel embodyingour inven- A tion. Fig. 2 is an enlarged detail cross-seetion throughthe folded seam. Fig. 3 shows the ordinary7 formof seam prior to beinglongitudinally grooved according to ourv4 inven- 5 tion. Fig. 4 is anenlarged sectional AView illustratingl the grooving step or operationand showing the chuck or head for supporting the inner side or wall ofthe seam and the grooving-roller for forming the groovein the :o outsideof the seam. Fig. 5 is a detail view showing the form oftheseaming-flanges on the can-.body and can-head before the double vorother seam is formed. Fig. 6 shows the rst step of the folding operationinforming the double seam;A and Figs. 7,- 8, 9, and 10 show thelongitudinal groove formed in 'difv-A l ferentpositions on the outsideof the seam, the latter (Fig. l0) showing the seam provided with twolongitudinal grooves instead 2o of one. i

In the drawings, @represents the can-head, `l) its coun'tersink orupright flange, and dits seeming-flan ge. y c represents the canbody,and e its seaming-flange, the same being shorter and narrower than thescathing-flange d on-the head (t, so' that said flange d may fold overthe .liange e. i

In practicing our invention the lseamingflanges d and e of the candieadand can-body are rst bent, folded, rolled, or formed into a folded seamF, preferahly'a double seam, substantiallyas illustrated in Fig. 3, and

, having a Vseries of three or more,'preferably' 35 five, folds,layers,`or thicknesses, l, 2, 3,4, ando, counting from the outside tothein.-

.side, the seam being formed in the usualway by a setof two or moresuccessively-operating and suitably-shaped double-steaming roll- 4o 'ersacting in conjunction with a 'chuck or head, as N, which fits insidethe-countersink of the canhead. The seaniing-roliersopen,

ate to c url or fold the projecting portion of the seaming ange d ofthe' can-head over 45. and around the'seaming-flange e'on the can- .l'body and to bend the two down against the exterior wall of the canbody.After the seamFisthus formed or simultaneously with its finishing oneside thereof, preferably its `5.o outside, is provided withalongitudinal groove f,.extending the length of the seam or around thecan, this being-done by a narrow bead o r ribm ou the finishing-roller Mof the:

seami'ng'mechanism in connection with the chuck or head N, which fitsinside of the countersink of the can-head and supportsand maintains inits original smooth shape the .p innermost fold or wall 5 of the seam F,while the outermost folds l 2 lare longitudinally 6.o groo'vedby theaction-of the bead or rib m ofl "iif the seaming-roller M. The rib orbead m may-be provided on the final or finishing roller of the ordinaryset of double-steaming rollers heretofore in use, or an eXtraseamingroller provided with such head or rib 'm may -be employed as theribbed 4or beaded roller M, ifdesire'd. The longitudinal groove f in theouter folds of the seam nlmypreferably be centrally located-'in respect,to the width of the seam asa Whoe,as illustrated in' Fig. 2, though itsposition on the seam inlay be varied without departing from ourinvel-.tiOn-as will be readily understood from the d ralwings Figs. 7,8, 9, and l0. y

The longitudinal groovef, formlgd in one side ofthe seam andextendingincisi-,brought` one or more of its folds l 2, while onepr more'of the folds 5 4 of the seam on the .dipposte side thereof aremaintained in their original plain smooth shape during the gi'oovingOpel ation has the effect to materially reduce-,Lbs thickness ofthe seamas av Whole along the into the most close intimate metal-temetailcontact the superimposed surfaces ofthe sev-i eral folds or layers l, 2,3,44, and dof the seam' and to effectually close up the most minute 0rhair-like crevices or passages that would otherwise be left, and thus tomake the seam perfectly secure and herlnetically tight.

It will be'understood that the operation and effect of thegrooving-roller M, having the bead or rib m in conjunction with thesup,- porting chuck or head N on the opposite sideof the seam whichresists the thrust ofv the bead of the grooving-roller, is to compress'and compact the seam and reduce itsthickness as .line of itslongitudinal groove and toforuga.

awhole along the line of the' groove and not simply to form acorrugation, groove, or bend extending through all the thicknesses oftheseam from one side thereof' to the other, as would1 be the case if oneor'more folds of the seam 4were not supported and maintained in eration,and thus prevented from yielding unf der action of the annular rib orbead m of the grooving-roller M. Y f

We'have usedtheterm foldsasin`dicat lng the Several snperpgsed layersorhick.. nesses of the seam, and this applies Whether theseamis of aroll type and substantially circular in cross-section (except for thegroove j) or more ory less oblong in cross-seetion, as shown in thedrawings. Y

In our invention the external grooving operation has or may have'theeect to thin or IOO ftheiroriginal shape during the grooving opv fr roreduce the thickness of the outer folds or layers of the seam along the4line of theexter-l nal longitudinal groove f; but, this is attended with4no injury, as the groove gives the seam a stronger form. .Thelongitudinal' groove f 'also gives the seam andthe can asa Whole a neatfinish.

As in our invention the inside'face or wall of the seam has noindentation, groove, projection, or corrugation therein, ,but is smoothand plain, the external groovingoperation of course ,does not lock thecan to the chuckhead, as would be the case if the samewere indented',grooved, or corrugated 0n both itsv inside and outside faces and it'were'attempt- -ed to so indent, groove, or corrugate it from theoutside while supported onthe inside by the chuck-head, as .done in ourinvention.

Having thus fully described our invention,

what we claim as new, and desire to securel by Letters Patent, is y l. Asheet-metal can comprisinga head and' body, and a solderless folded seamuniting the saine, said seam having alongitudinal groovel in one outeror exposed side thereof extending vthe length of the seam around thecan, and a plain smooth wall on its opposite outer or exposed side,substantially as described.

2. In a sheet-metal vessel, a solderless folded seam comprising three ormore folds or thicknesses and having in lfhe outer thickness on one sideof said seam a longitudinal groove and the outer thickness on the otherside of said seam plain 'or smooth, substantially as described.

folds on the opposite side thereof, substantially as described.

4c. A sheet-metal vessel having a solderless seam comprising two or morelongitudinally and correspondingly grooved folds on one side of theseam, and two or more plain smooth folds on the opposite side of theseam, substantially as described.

5. A sheet-metal vessel having a solder-less seam composed of three ormore superimposed folds, two or more of which on one side of the seamhave a longitudinal groove and the other or others of which are plainand smooth, substantially as described.

In testimony that we claim the foregoing we have hereunto set our handsthis 20th day of March, 1903.
